The AleHu client has been tested with the following setups:
The client was tested under some heavy load: receiving several messages having attachments up to 720 MB and simultaneously transmitting several messages having large attachments, too. In the latest versions of the client these messages could be transmitted to the last bit without any crashes, showing only occasional timeout exceptions.
Besides, several tests were made using clients that went online and offline over and over again. Partially transmitted packets were rescheduled by the clients until every packet had completed its traversal from sender to receiver.
To put it in at nutshell: the latest versions of the client seem to be pretty stable and robust and hopefully beta testing can soon be completed to launch a first production version of the AleHu messaging system!
